To aZZ whom iv may concern.- r

Be it known that I, HERBERT L. KEY s, a citizen of the United States, residing at Hackensack, in the county of Bergen and State of New Jersey, have invented a new and useful Improvement in Window-Shade Carriers, of which the following is a specification.

The object of this invention is to provide means for carrying the window-shade and its roller bodily up or down in the window-opening and holding the same inthe desired po-' sition.

In carrying out my inventionI provide slotted bars with racks, which bars are adapted to be secured upon the stop-bead or opposite An extensible cross-bar is provided with a pinion on each end, the pinions being within the slotted bars A portion of the extensible cross-bar is preferably made tubular, and at this point the tubular parts are of the same and coinciding sectional configuration. Bearing-blocks are provided with recesses to engage the journaled ends of the cross-bar adjacent to the pinions. These bearingblocks are within the slotted bars, and to one of them is provided a rod, to the lower end of which is connected a screw-clamp by which the bearing-block can be held in any desired position to which it may be moved. These bearing-blocks above and below the extensible red are perforated to receive the respective pivot ends of the fixtures upon the shad eroller.

In the drawings, Figure 1 is an elevation and partial section representing myimprovement. Fig. 2is a sectional plan of the same at the line 00 00. Figs. 3 and 4 represent face views of the bearing-blocks, and Fig. 5 is a section at the line 'y y of Fig. 1.

The slotted bars Ct at are to be secured in any desired manner upon the stop-beads or upon the opposite inner or outer faces of the window-casing, the details of the manner of fastening being immaterial. These bars are preferably made of sheet metal, and within each bar is a rack 2, adapted to engage a pinion b or b. The racks 2 may be formed of separate strips of metal secured within the slotted sheet metal bars, or they may be formed by perforating the slotted bars themselves. These pinions b b are at the ends of aniexten'sible cross bare, which bar is preferably made tubular in the middle portion at 3, one tube sliding within the other, so as to accommodate the carrier to different widths of windows. These tubes sliding or teleseoping the one within the other are preferably made of parts of the same and coinciding sectional configuration. They may, however, be made with longitudinal corrugations 4, the corrugationsof the inner tube sliding within the corrugations of the outer tube, as thereby a stiifer telescoping device is produced.

Within the slotted bars a a are the bearing-blocks d cl. (Shown in Figs. 3 and 4.) These bearing-blocks are recessed about centrally in one edge for the respective ends or journals of the extensible cross-bar'adjacent to the pinions. These bearing-blocks are received within the slotted bars with the pinions and slide therein,so as tokeep the teeth of the pinions properly in gear with the racks. These bearing-blocks are made alike, except that the block (1 is provided with an extension or rod 6, to the lower end of which another block 6' is secured. The block e is also within the sliding bar, and to it is secured the threaded stem fof the clamping-screwf. The object of this clamping-screw is to secure the bearing action also secures the bearing-block d in the slotted barn, because the pinion at one side being stopped and the extensible crossbar held, it is also held at the other side.

In the bearing-blocks d d, above and below the position occupied by the extensible crossbar, there are openings or ends adapted to receive the fixtures at the ends of any ordinary curtain or shade roller. These openings are adapted to receive an ordinary curtain or shade roller or the fixtures of the well-known spring-actuated shade-roller, as at h. These openings are shown at 5, and the shape of the same is immaterial so long as they are adapted to receive the pivots of the ordinary or spring-actuated shade-roller.

It will now be understood that by slackening the screw-clamp f the rod and bearingblocks (1 e can be moved up and down in the slide-bar a with freedom, and in so doing the ing-block d to the slotted bar 0b in any posi- I tion to which it may be moved. This clamppinion b will be rotated, and the cross-bar 0 will be rotated by this pinion and will in turn rotate the pinion Z) at the other end thereof and upon the other side of the window, which pinion, turning in contact with the rack-teeth of the slotted bar a, will carry the bearing-block d bodily up and down in the slotted bar a to the same extent that the bearing-blocks d e are carried by hand at the other side of the window-frame, thus obtaining uniformity of movement and parallelism of the parts. The slotted bars a a may be of any desired length. They are, however, preferably long enough to extend from the upper part of the window-easin g down to and below the meeting-rails of the sashes, so that the curtain or window-shade may occupy any intermediate position between these two points that may be desirable either for light or when the upper sash of the window is lowered for air. In whatever position the extensible cross-bar and attendant parts may be placed in the slotted bars the windowshade can be drawn down to the bottom of the window, so as to exclude light and view and at the same time leave the upper part of the window open to light or air, or both.

I claim as my invention 1. In a window-shade carrier, the combination with the slotted bars and their racks, of pinions engaging the racks, bearing-blocks within the slotted bars and receiving the journals of the pinions, an extensible crossbar upon whose respective ends are the pinions, said bar being made of two telescoping tubular portions of the same and coinciding sectional configuration, and a clamp for holding the bearing-block at one side of the window, substantially as set forth.

2. In a window-shade carrier, the combination with the slotted bars and their racks, of pinions engaging the racks, bearing-blocks within the slotted bars and receiving the journals of the pinions, an extensible crossbar upon whose respective ends are said pinions, the same extending across the window between the slotted bars and a clamp for holding the bearing-block at one side of the window, substantially as set forth.

3. In a window-shade carrier, the combination with the slotted bars and their racks, of pinions engaging the racks, bearing-blocks within the slotted bars receiving the journals of the pinions and having openings or n otehes above and below said journals adapted to receive the fixtures upon the ends of the window-shade roller,an extensible cross-bar upon whose ends are said pinions and extending across the window and by which the pinions are rotated and the respective bearing-blocks moved uniformly and parallel to one another, and a clamp for holding the bearing-block at one side of the window, substantially as set forth.

Signed by me this 2d day of September, 1897.
